I am looking at new wheels for my 09 taco trd double cab.i am woundering what the bolt pattern is. Also what is hub centric and does it concern me? also what is offset? the offset on the ones i'm looking at are 0mm. thanks

bolt pattern is a 6 on 5.5 on a 4x4..and hub centric is where the center bore hole of a wheel is made to match up with the hub diameter of the vehicle; the wheel is then centered by the center hole, rather than the lug nuts. And the Offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel. The offset can be one of three types, zero, positive, or negative.
